Gripping surface that has no errors? (7)
I believe the answer is:
nonslip
'gripping' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'surface that has no errors?' is the wordplay.
'surface' becomes 'lip' (lip is a kind of surface).
'that has' means one lot of letters go next to another.
'no errors?' becomes 'nons' (I am not sure about this - if you are sure you should believe this answer much more).
'lip' put after 'nons' is 'NONSLIP'.
Can you help me to learn more?
(Other definitions for nonslip that I've seen before include "unlikely to slide" , "Designed not to slide unexpectedly" , "Preventing sliding" , "Designed for secure footing" , "(Of surface) affording a strong grip" .)
